This work (Bulletin No. 55) is one of a series of papers intended to
illustrate the collections belonging to or placed under the charge of
the Smithsonian Institution and deposited in the United States National
Museum.

The publications of the National Museum consist of two series—the
Bulletin and the Proceedings.

The Bulletin, publication of which was commenced in 1875, is a
series of elaborate papers issued separately and based for the most
part upon collections in the National Museum. They are monographie
in scope and are devoted principally to the discussion of large zoolog-
ical groups, bibliographies of eminent naturalists, reports of expedi-
tions, etc. The bulletins, issued only as volumes with one exception,
are of octavo size, although a quarto form, known as the Special
Bulletin, has been adopted in a few instances in which a larger page
was deemed indispensable. .

The Proceedings (octavo), the first volume of which was issued in
1878, are intended primarily as a medium of publication for newly
acquired facts in biology, anthropology, and geology, descriptions of
“new forms of animals and plants, discussions of nomenclature, ete.
A volume of about 1,000 pages is issued annually for distribution to
libraries, while a limited edition of each paper in the volume is printed
and distributed in pamphlet form in advance.

In addition, there are printed each year in the second volume of the
Smithsonian Report (known as the Report of the U. S. National
Museum), papers, chiefly of an ethnological character, describing col-
lections in the National Museum.

Papers intended for publication by the National Museum are usually
referred to an advisory committee, composed as follows: Frederick
W. True (chairman), George P. Merrill, Otis T. Mason, James EK.
Benedict, Walter Hough, T. W. Stanton, Leonhard Stejneger, and
Marcus Benjamin (editor).

A CONTRIBUTION TO THE OCEANOGRAPHY OF THE PACIFIC

By James M. Fuint,
Medical Director, U. S. Navy; Curator, Division of Medicine.

INTRODUCTION.

In the early part of the year 1899 the U.S. 8. Wero, a steam collier
of 4,925 tons displacement, which had been purchased for use during
the Spanish-American war, was fitted out by the Navy Department,
equipped with the necessary apparatus, and dispatched from San
Francisco under the command of Commander Charles Belknap, U. 5.
Navy, with instructions to survey a route for a telegraph cable between
the United States, the Philippine Islands, and Japan.

On account of the illness of Commander Belknap, he was relieved
from command on the arrival of the ship at Manila by Lieut. Com-
mander H. M. Hodges, U. 8. Navy, who remained in charge of the
survey until its completion.

Several previous surveys having established a satisfactory route
between the coast of California and the Sandwich Islands, the actual
work of the Vero began at Honolulu, from which port the ship sailed
on the 6th day of May, 1899.

The following table of dates, distances, and number of soundings
furnishes an abstract of the cruise:

From the above table it appears that the distance sailed while on
actual survey work was 21,519 geographical miles and the number of
soundings 2,074, or an average of one sounding at every ten miles of
distance run. Measuring the direct course of the survey, 6,144 knots,
there are records of soundings averaging one every three miles of the
route.

PLAN OF SURVEY.

The instructions regarding the survey were, in brief, to follow as
nearly direct lines as practicable from Honolulu to Midway Island,
thence to Guam, thence to Luzon, and also from Guam to Japan...
Soundings were to be taken on the outward voyage at intervals of 10
and 2 miles alternately; temperatures of the air, surface and bottom of
the sea to be recorded; currents noted; samples of bottom material
brought up in a sounding cup to be preserved, etc. The return
course was planned to cross the primary route zigzag at angles of
45°, the sides of the angle to be 20 miles in length; soundings to be.
taken at the apices of the angles. This plan was effectively carried
out, modified somewhat in detail by circumstances, especially as
regards intervals between soundings and detours from the main line
in order to develop marked irregularities of the contour of the ocean
bed. In this manner an examination was made of a belt of ocean
about 14 miles wide and over 6,000 miles in length, unequaled in
thoroughness, so far at least as soundings are concerned, by any sur-
vey hitherto made of an ocean tract.

OCEANOGRAPHY OF THE PACIFIC. 3
TRACK. '

It would be unnecessary for the purpose of this study to attempt to
present in detail the exact courses followed by the vessel, which were
at times quite erratic, in the effort to find the most feasible location
for the cable. It is to be understood, therefore, that the accompany-
ing track charts do not represent the exact courses of the ship nor the
line determined upon for the cable or followed in the laying of it.
The stations charted, however, are supposed to be accurately located.
Before preparing the charts certain stations on the outward voyage
were selected for careful examination of bottom material. The con-
siderations governing the selection were chiefly the depth, the macro-
scopic appearances of the bottom specimens, and the distances. These
stations were afterwards plotted and connected by a continuous line.
In a few instances outlying stations of especial interest have been
indicated on the charts, and a serial number and depth given for each.
On the first or diagrammatic chart the station numbers included
within each five degrees of longitude or latitude are given for both the
outward and homeward voyages. By means of this index it is easy to
locate approximately any station mentioned in the record.

DEPTHS.

The graphic representation of the contour of the ocean bed along
the course of this survey is less simple and satisfactory than usual,
because of the breadth of track explored and the large number of
soundings recorded. It should be noted, in examining the contour
charts appended, that-the lines are drawn from the localities indicated
on the track charts as stations selected for special examination of
bottom material, and one of the principal determining factors in the
selection was that of depth. Therefore, the contour charts may be
said to represent the extremes of elevation and depression along the
main line of the outward voyage only, without taking into account
intermediate or outlying irregularities of surface. The omitted sta-
tions can be easily supplied from the record if greater detail is desired.

‘Leaving the island of Oahu of the Hawaiian group, the depth
increases quite rapidly until it reaches about 2,500 fathoms. This
depth is reached less than 30 miles due north of the island.’ From
this point nearly to Midway Island there is a comparatively level
plain, broken only by two or three outlying peaks from the moun-
tain range whose highest summits show themselves as small islands or
reefs a little to the westward of the line of survey. One of these
peaks appears at station 93, where there is a sharp rise to 1,463
fathoms, which, however, as rapidly falls away to the normal level a
few miles tothe northward. <A smaller projecting spur is indicated at
station 106, 2,002 fathoms. Another sudden rise to 1,726 fathoms

4 BULLETIN 55, UNITED STATES NATIONAL MUSEUM.

appears at station 124, followed by depressions to more than 2,600
fathoms a few miles away, both to the westward and northward.
With these exceptions the range of variation is practically between
2,500 and 3,000 fathoms for tbe whole distance until the immediate
Vv ecology of the Midway Islands is reached.

About 30 miles to the southward and westward of Midway Island a
very bold peak was discovered rising abruptly from the ocean floor,
2,000 fathoms below the sea level, to a height only 82 fathoms below
the surface.

Passing from the vicinity of Midway Islands a nearly level plain is
found, extending about 1,000 miles to the westward, upon which the
extremes of depth of water are 2,926 and 3,382 fathoms. About mid-
distance between Guam and Midway Islands what is apparently a
mountain range is encountered, extending over 3° of longitude, with
varying depths from 3,000 to 720 fathoms. On the westward side of
this mountain range another plain below the 3,000-fathom line extends
a distance of about 300 miles. From the western limit of this plain
until Guam is reached the contour is quite irregular. Extensive detours
both north and south of the direct course developed a mountainous
region, with peaks rising to 689 fathoms below the sea level, and val-
leys descending to a depth of more than 5,000 fathoms. Four sound-
ings below the 5,000-fathom line were made, with the record of 5,070,
5,101, 5,160, and 5,269 fathoms. These were in the abyss now known
as the ‘‘ Nero Deep.” The last-named sounding was numbered 1488,
in latitude 12° 43’ 15” north, longitude 145° 49’ east, about 75 miles
east-southeast from the island of Guam, and is the deepest sounding
ever recorded, being only 66 feet less than 6 statute miles.

From Guam to Luzon the ocean bed is for the most part gently
undulating, at depths varying from 2,500 to 3,000 fathoms. About
120 miles west of Gaum (station 688) there appears a sharp elevation to
1,346 fathoms, which however soon subsides to the normal depth of
about 2,700 fathoms. Again, about 600 miles from Guam (station
760) a rise to 1,560 fathoms is encountered. From the data at hand
this latter would seem to be a peak rather than a mountain range,
since soundings east, west,and south show speedy subsidence to nearly
normal depths. At station 784 the depth reaches 3,547 fathoms, with
several soundings in that vicinity below 3,000. Approaching Dingala
Bay on the east coast of Luzon and about 120 miles distant (station
864) another peak appears with summit only 821 fathoms below sea
level. In this instance also, soundings north, east, and west soon
develop normal depths.

From Guam to Yokohama the route lies to the westward of the
Ladrone Islands and to the eastward of the Bonin group. For a dis-
tance of 500 miles or more from Guam the soundings show a gently
undulating plain at an average depth of about 2,100 fathoms. Between

OCEANOGRAPHY OF THE PACIFIC. 5

latitude 21° 45’ and 22° 8’ north and longitude 143° 45’ and 148° 20/
east three sharp peaks arise along-a line about 35 miles in length
and northwesterly in direction. On the first, or most southerly, the
sounding record is 483 fathoms; on the second, about 18 miles away,
the record is 888 fathoms; and on the third, 20 miles farther to the
northwest, 802 fathoms. There are valleys 1,000 fathoms deep
between these peaks. The indications point to a continuous range of
‘mountains connecting the Ladrone Islands with the Bonin group.
After dropping down the eastern slope of the above-mentioned peaks,
the depth increases by an easy gradient to 3,595 fathoms at station
1095, rising and falling gently until at station 1126 a sounding of 972
fathoms locates an outlying spur from the Bonin range. Still farther
to the northward and westward, at station 1135, the bottom drops
to 3,421 fathoms, followed by gentle slopes up to 1,500 and down to
2,900 fathoms, until the Gulf of Tokyo is reached.

GRADIENTS.

In computing the gradients from station to station serially on the
outward voyage only, involving 1,100 soundings, sixty-nine localities
only are found where the gradient exceeds 10 per cent. These higher
grades are for short distances only, averaging less than 5 miles, and
confined toa few regions, especially to the vicinity of Midway Islands,
Guam, and the mountain range halfway between the above-mentioned
islands. Of the sixty-nine localities showing a grade above 10 per
cent, fifty have an incline between 10 and 20 per cent, eleven between
20 and 30 per cent, and six between 30 and 40 per cent. At the
entrance to Port Tarafofo, on the east coast of Guam, two soundings
one-fourth of a mile apart show a difference of depth of 123 fathoms,
equivalent to a gradient of about 51 per cent. Also on the declivity of
the peak southwest of Midway Islands, which rises to 82 fathoms
beneath the surface of the water, there is a change of depth of 1,269
fathoms (7,614 feet) in a horizontal distance of 1.8 sea miles, a gradient
of 70 percent. With these few and localized exceptions the bed of the
Pacific Ocean, as developed by this survey, though rising here and
there near to the sea level, and again descending to depths of 5 or 6
statute miles, follows easy gradients. On the great plain to the west-
ward of the Midway Islands, 1,000 miles in breadth, the average
gradient is less than 1 per cent—in one instance only rising to 4.5 per
cent, for a distance of 2 miles.

TEMPERATURES.
AIR AND SURFACE WATER.

The temperature of the air on board the ship, and of the water near
the surface, was taken at nearly all the sounding stations. These sta-
tions numbered, on the average, about ten each day on the outward

It will be seen from the above table (1) that the average temperature
of the air, in these regions uninfluenced by the proximity of other
than small and scattered islands, varies little from that of the contig-
uous waters of the sea. (2) Thatin the region between the Hawaiian
Islands and Guam the difference between summer and winter temper-
atures of both air and water is quite small. On the round trips
between Guam and Luzon and Guam and Yokohama, each having
occupied only about two months, there are not sufficient data for esti-
mation of seasonal changes in these regions. In considering extremes
of temperature, it should be remembered that Midway Islands and
Yokohama are both in considerably higher latitudes than the Hawaiian
Islands, Guam, and Luzon, and, other conditions being equal, the low-
est temperatures would naturally be found in the higher latitudes.

Thus, the surface temperature in the vicinity of Oahu is about
75°.4, while in the vicinity of Midway it falls to about 71°. Leaving
Midway with an average of 70°.4 at the first eleven stations, the sur-
face temperature rises to an average of 84°.8 at the last thirty-one
stations approaching Guam. From Guam until within 300 miles of
Yokohama the surface water remains near 85°, falling to an average
of 76°.7 at the last eighteen stations.

The diurnal variations of temperature were of course greater in the
air than in the water near the surface. The normal range of variation
was from 4° to 7° for the air, and 1° to 3° for the surface water. The

extreme range of air temperature for any one day was 14°, January

17, 1900. There is also one record of 13° August 30, 1899, four of

How much the recorded air temperatures may have been affected by
local conditions, such as radiation from the heated deck at midday, or
evaporation from a wet deck, it is impossible to estimate.

BOTTOM TEMPERATURES.

No serial temperatures were taken. Observations of bottom tem-
peratures on both outward and homeward voyages to the number of
604 are reported. In drawing conclusions from the records of these
observations, some allowance should be made for the difficulties attend-
ing the measurement of temperatures at great depth, because of the
delicacy of the instruments, the enormous pressures to which they
are subjected, the shocks to which they are liable, and the vibration
tending to displace the index as the thermometer is drawn up. Pro-
fessor Tate says:” ** The circumstances under which thermometers are
let down and drawn up again at sea are extremely unfavorable to
accuracy of observation.” In the column of remarks, on the Vero
records, it is repeatedly noted that ‘* Thermometer failed to work.”
So that where striking variations from normal temperatures, at given
depths and in neighboring localities, appear on the record, the proba-
bilities seem largely in favor of the assumption of instrumental, or
possibly clerical, errors rather than of great eccentricities of tempera-
ture, unless there should appear to be something in the local condi-
tions reasonably to account for the variation.

The high temperature average, between 800 and 900 fathoms, is due to
the exceptional record of 41°.1 at station 1225, in immediate proximity
to the volcanic island of Oshima or Vries Island, at the entrance
to the Gulf of Tokyo; also two records of 39° at stations 1569 and
1570, on the summit of a high peak or ridge about 450 miles to the
eastward of the island of Guam. The average of the other four
records is 36°.97.

fathoms there is record of 388° at station 1678, and 37°.3 at the adjoin-
ing station 1677. These two stations are on one of the peaks of the
mountain range in midocean between Midway and Guam. There are
no other records of temperature above 37° at these depths.

Only two stations between the 1,500 and 2,000 fathom line record
temperature above 37°, namely: Stations 1000, 39°.3 and 1009, 37°.3,
about 60 and 120 miles, respectively, to the northward of Guam. There
is probability of error in one or both of these observations.

In making up the average of temperatures between 2,000 and 3,000
fathoms, 16 of the 266 observations have been omitted from the
calculations. In some of these cases ‘‘incorrect” is noted on the
original record; in others, the probability of instrumental or clerical
error is so much greater than the probability of existence of local
conditions capable cf producing such deviations from the normal
range of temperature as to justify their exclusion. The omissions are
stations 131 (44°), 188 (519.7), 140 (44°.8), 232 (39°.4), 243 (38°.9),
477 (38°.8), 479 (449.5), 719 (67°.6), 722 (67°), 723 (67°), 962 (87°),
1508 (33°), 1511 (38°), 1512 (84°), 1513 (84°), 1514 (34°). The last five
of these rejected observations were taken by a thermometer concern-
ing which it is noted: ‘‘ Correction not known.” This thermometer

being replaced by another, the temperatures are again recorded at the
normal of 35° and above.

Of the 188 temperatures taken at depths from 3,000 to 4,000 fathoms,
10 have been excluded from the computation of averages, for the
reasons given above. They are the following: Stations 239 (52°), 244
(38°), 251 (88°.9), 257 (60°), 312 (38°.4), 422 (87°.8), 489 (40°.2), 501
(87°.4), 790 (82°), 809 (22°.9).

Three temperature observations were made between 4,000 and 5,000
fathoms, and two at depths of 5,070 and 5,101 fathoms respectively,
all in the abyss southward and eastward of Guam.

The obvious inference from the above computation is that the tem-
perature of that part of the Pacific Ocean covered by this survey falls
rather rapidly from the surface to about 600 fathoms, then very slowly
to about 2,500 fathoms, where the normal temperature varies but
slightly from 35° F. Below 2,500 fathoms there appears to be a
slight rise of a fraction of a degree. But it is open to question if
this apparent rise may not be due to the effect of the enormous pres-
sure of three to five tons to the square inch, at these great depths,
upon the instruments.

CHARACTER OF BOTTOM.

The character of the bottom indicated on the record by abbrevia-
tions, refers only to the gross appearances of the material recovered
in the sounding cup, when fresh from the water. Translated into the
terms of the usual scientific classification, the brown mud (‘‘br. m.”’)
of the record is generally the red clay of the oceanographer, or rarely
volcanic mud from deep water. With few exceptions what is desig-
nated coral sand (‘‘co. s.”) is globigerina ooze. The rock (R. or r.)
has, in every case examined, proved to be fragments of pumice or
manganese-iron concretions; the black specks also are almost always
particles of manganese iron. Except in the immediate vicinity of a
shore, gravel (G. or gvl.) is, in this part of the ocean at least,
coarse volcanic débris which has been distributed by wind or wave all
over the sea, and has finally found its way to the bottom. The sand
(S. or s.) so often noted consists of finer mineral particles from the
same source as above-mentioned, except near the shores of islands.

Other abbreviations than those just given, used in the columns for
character of bottom, refer to color, size, etc.—bk=black; br=brown;
dk=dark; gy=gray; It=light; rd=red; wh=white; y. or yl=yellow;
ers=coarse; fn=fine; hrd=hard; rky=rocky.

tween high and low water

2. Shallow- water de-

Only 22 soundings are recorded within the 100-fathom line, and from
several of these no specimens have come to hand. Pr safer , there-
fore, only deep-sea deposits have to be considered in this report.

Red clay.—Of the above-mentioned classes of deposits by far the
most extensive is red clay. This, as it appears in the specimens
received, is a smooth, sticky mud, varying in color from light yellowish-
brown (fawn color) to dark chocolate, these colors being somewhat
modified in individual instances by exposure to light, and especially
by drying. In composition it consists of (1) extremely fine, amorphous -
particles of clayey matter, mostly hydrated aluminum silicate and the
débris of other minerals; (2) the remains of calcareous organisms
(foraminifera, coccospheres, and rhabdospheres), this constituent, how-
ever, rapidly disappearing at depths of about 2,500 fathoms; (3) siliceous
organic remains (sponge * spimiligs, radiolarian skeletons, ancl the frus-
tules of diatoms; (4) mineral fragments, mostly of volcanic origin, at
least in this part of the ocean; and (5) certain products of local chem-
ical reactions, especially nodules, coatings, and grains of manganese
peroxide, crystals of phillipsite, and particles of palagonite. The pro-
portions of these constituents vary greatly along the line and even
from station to station. As has been stated, foraminifera disappear,
for the most part, at depths below 2,500 fathoms; radiolaria are likely
to be more numerous in the deeper waters; diatoms are nearly every-
where, but only occasionally in great numbers. Mineral fragments

may be so minute in some specimens tet they pass over almost

OCEANOGRAPHY OF THE PACIFIC. let

entirely in the fine washings, while in others they may be compara-
tively coarse. Volcanic glass is sometimes present in notable quantity.
Manganese-iron nodules, and concretions upon other minerals, are
almost universally present. They are the black specks (‘* bk. sp.”) so
frequently recorded on the official records, the larger ones being gener-
ally referred to as rock (*‘ R.”) Phillipsite is a freqent constituent.
It is found as quite perfect crystals, single, twinned, or multiple, or
more frequently as spherules made up of crystalsarranged radially. The
simpler forms are found in great numbers at station 331 (2,997 fathoms),
and the spherules at station 495 (3,204 fathoms). Vertebrate remains,
teeth of sharks and other fishes, and otoliths, have not been observed
in this or other deposits, though carefully looked for.

This red clay deposit is indicated in 75 per cent of the soundings
from which specimens were received (1,043 out of 1,394), between the
Hawaiian Islands and the Philippines. It is conspicuously absent
except at three stations along the line from Guam to Yokohama, being
replaced at corresponding depths by voleanic mud. It is probable
that this belt of yoleanic mud does not extend far from the range of
volcanic islands along which the cable route passes.

The least depth at which a distinctly red clay deposit has been noted
is at station 680—2,010 fathoms. It is always found inabysmal depths.
Ordinarily, as the contour line rises above the 2,500-fathom mark foram-
inifera rapidly increase in numbers and perfection of form, and soon
justify the classification of the deposit under the head of globigerina ooze.

Globigerina ooze. —Globigerina ooze is defined as a deposit containing
over 30 per cent of calcium carbonate, principally in the form of
minute shells of foraminifera. Other organic remains commonly
found in this deposit are sponge spicules, radiolaria, diatoms, and the
very minute coccoliths and rhabdoliths. Asa rule, in this part of the
Pacific Ocean globigerina ooze will be found wherever the depth is
less than 2,200 fathoms. The exceptions are found in the region of
volcanic islands or submarine volcanic peaks where the foraminifera
seem to be overwhelmed by volcanic sand, and in the vicinity of island
shores where coral sand or blue or green mud may predominate. The
elobigerina ooze, wherever found on the line of this survey, is composed
principally of the few species (about 20) of foraminifera known to be
pelagic. Bottom living species are rare and individually few in num-
ber. The proportion of mineral matter, other than calcium carbonate,
in this deposit is relatively small. Manganese concretions are gener-
ally present and sometimes quite numerous, and fragments of pumice
are common. Crystals and spheruies of phillipsite are often noted.
The finer mineral fragments are quite lost in the mass of foraminifera,
but appear when the latter are dissolved out with acid. At one sta-
tion—648, 1,757 fathoms—the cavities of very many of the shells were
found to be filled with a siliceous deposit forming complete casts of the

Wy) BULLETIN 55, UNITED STATES NATIONAL MUSEUM.

interior of the shells, even to the minute foramina. These casts are
also noted twice in volcanic mud (stations 991 and 1065). Doubtless
examples of these casts might be found in many other samples of
globigerina ooze.

Diatom ooze.—Diatom ooze is the name given to a deep-sea deposit
of which the principal constituent is the siliceous frustules of diatoms.
‘Previous to this survey such a deposit had not been found in any
tropical waters, and was supposed to be ‘‘ confined to the Southern or
Antarctic oceans, or to the northern parts of the North Pacific.”
Unexpectedly, therefore, many distinct patches of characteristic diatom
ooze were found on the line, especially between Guam and Luzon,
latitude 14° 28’ to 14° 50’ north, and longitude 136° to 130° 30’ east.
Along this tract, about 300 miles in length, diatom ooze was recovered
at stations, as follows:

Between Guam and Midway Islands diatom ooze of the same nature
appears at stations 559, 1710, and 1724. Also at stations 314 and 350
broken frustules of Coscinodiscus rex are noted.

As may be seen from the above table, the depths varied from 2,432
to 3,658 fathoms. In appearance the typical examples ave greyish-
white in color, shading off to a pale yellowish-brown wherever the
fine red clay mud is present in any considerable proportion. In con-
sistence it is mucilaginous, but is readily disintegrated by shaking with
water. Radiolaria are generally rather numerous in this deposit.
Mineral fragments are few. In all the specimens examined the
diatoms belong almost exclusively to a single species identified by
Professor Mann as Coscinodiscus rex Wallich. This is one of the
largest diatoms known, having a diameter of about 0.8 millimeter,
and is plainly visible to the naked eye. In form it resembles a minute
pill box, with slightly rounded corners. The two valves (bottom and
cover) are held together by a broad circumferential band. The valves
are extremely thin and fragile, and the markings exceedingly delicate.

OCEANOGRAPHY OF THE PACIFIC. 13

In some instances complete frustules are found, but usually the valves
are separated and often much broken. A peculiar feature of this
deposit is the strict limitation of the patches. Nearly pure diatom
ooze may be recovered from one station, and at the next, five miles
away, not a diatom appear in the desposit.

Radiolarian ooze.—No well-marked example of radiolarian ooze has
been found in the specimens examined. Though radiolaria are noted
in most of the samples, nowhere do they appear as a dominating con-
stituent of the deposit. They are most numerous in the diatom oozes,
where they are generally conspicuous by the number of individuals,
but the number of species represented is not great.

Volcanic mud.—This is a deposit found in the neighborhood of
volcanic islands or submarine volcanic peaks. Its characteristic con-
stituents are pumice, glass, ashes, and the débris of voleanic rocks.
It is often mixed with a considerable proportion of foraminifera when
taken from depths less than 2,000 fathoms. Most often it is dark gray
in color, and is readily disintegrated by shaking with water, being
devoid of the sticky quality of red clay. This deposit is noted about
the islands-of Oahu and Guam, and nearly the whole distance from
Guam to Yokohama, where the route passes along nearly parallel to
the Ladrone and Bonin groups of volcanic islands, and at no great dis-
tance therefrom. The most conspicuous mineral constituent of this
deposit is volcanic glass. It appea-ss in various forms, the most fre-
quent being the fibrous or filamentous variety. This has the appear-
ance of having been drawn out when in a plastic state, sometimes into
long, extremely fine threads, more commonly into larger threads or
ribands, furrowed longitudinally, broken into short pieces, and always
colorless and transparent as the finest artificial product. Another
form 1s more massive, ragged in outline, dark brown, translucent,
with numerous large, rounded cavities, and not so conspicuously sug-
gestive of having been drawn out while cooling. <A third variety
consists of very fine, angular, perfectly transparent and colorless
fragments, which often make up the bulk of the washed sediment.
Red palagonite, coating fragments of other minerals is more fre-
quently present in this deposit than in any other.

Blue mud.—Blue mud is the deposit generally found in inclosed or
partially inclosed seas, and in the waters bordering continentalland. It
is composed for the most part of the débris carried out from the land
by rivers or other currents. The few specimens collected by the Vero
are blue-black in color, on the sides of the vial exposed to the light of
a dark steel-blue with metallic luster, and iridescent. The color is
said to be due to the presence of organic matter and iron sulphide.
The odor of hydrogen sulphide is evident in all the well-corked vials
of this mud. Except in deep waters foraminifera are more or Jess
numerous. Radiolaria and diatoms are generally present, sometimes

in large numbers. Blue mud appears on the line of this survey only
off the coasts of Luzon and Japan.

Green mud.—Green mud is found under the same conditions as blue
mud. It is said to owe its color generally to the presence of the olive-
green mineral glauconite, but sometimes to the presence of organic
matter and its reducing action upon iron peroxide. In some instances
the green color of the specimens has turned a bluish-black since
recovery, and from present appearances would be called blue mud.
In all the specimens of green mud the tinge of green is faint, and the
greenish grains of sand comprise but a small part of the sediment.
A large part of the coloration must be due to extremely minute amor-
phous mineral matter, since the supernatant water in the settling-glass
remains cloudy and tinged with green after standing for an hour, and
is not cleared or decolorized by nitro-hydrochloric acid. No glauco-
nitic casts of foraminifera have been noted in these specimens. Green
mud is recorded at several stations in Dingala Bay, coast of Luzon,
and at all stations but one from No. 1217 to the anchorage near
Yokohama, a distance of about TO miles.
